'Steven Universe' season 4 return date, spoilers: Air date and synopsis for 'Gem Harvest' confirmed

A screenshot from the "Steven Universe" season 4 preview of "Gem Harvest" first released at the New York Comic-Con YouTube/Cartoon Network

It was revealed at the New York Comic-Con (NYCC) that "Steven Universe" season 4 will be back with new episodes this month, but no specific date was indicated, until now that is.

According to Geek Girl Authority, "Gem Harvest," episode 8 of the current season, will arrive on Nov. 17, just in time for Thanksgiving, which will be held on Nov. 24 this year.

It also came with a promotional image featuring the gang sans Steve looking at something unseen with their facial expression different from each other.

As teased in the "Steven Universe" season 4 sneak peek shown at the NYCC, Peridot and Lapis try to eliminate boredom in the barn by farming vegetables, but they were disappointed to learn the things they planted are not the same as gems.

Steven does not have the heart to see their hard work and excitement lead to a letdown, so he decides to create an animated pumpkin, which resembled a hybrid of a jack-o'-lantern and an adorable dog.

This "Steven Universe" season 4 episode will be 30-minute special, the second in the whole series ("Bismuth" from last season being the first one).

The installment is believed to be a Thanksgiving special, which might explain why the air date is close to the date of the actual annual holiday.

It is rumored that the "Steven Universe" season 4 episode 8 will see the rise of a new fusion between Peridot and Lapis, who fans believe have gotten close enough to summon one.

"Adventure Time" voice actress Ashly Burch is rumored to provide the voice of this purported new fusion, although nothing has been confirmed yet.

Cartoon Network has not even made an official announcement about the return date of "Steven Universe" season 4 and has only teased a November premiere.

"Steven Universe" season 4 will also feature a new episode titled "Three Gems and a Baby," which will feature a brand new Greg song.
